What forecasters said that day
The local office's own words before this small craft advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Los Angeles, CA wrote its last area forecast discussion before this small craft advisory went out at Dec 24, 9:11 PM PST, 2 minutes earlier.
Area forecast discussion, Dec 24, 9:11 PM PST, 2 minutes before
Area Forecast Discussion
National Weather Service Los Angeles/Oxnard CA
911 PM PST Fri Dec 24 2021
.SYNOPSIS...24/716 PM.
Periods of rain and mountain snow will prevail over the entire
area. Temperatures will be significantly below normal across the
region by midweek.
&&
.SHORT TERM (FRI-MON)...24/853 PM.
Broad cyclonic upper level flow will continue tonight in advance
of our next upper level trough which is expected to bring
an associated cold front through our region tomorrow afternoon
and night. Satellite imagery continues to show ample low level
moisture in the wake of today's passing storm system. Automated
rain gauges still showing a few light showers lingering across
the area this evening, mainly in the foothills and mountains.
Overnight into tomorrow morning, the cyclonic flow aloft will
gradually increase, while model cross sections show increasing
low level moisture. HREF ensemble solutions also support this
idea in regards to Pops, especially over LA county. As a result,
have bumped up pops a bit for overnight into Sunday morning,
especially the foothills and coastal slopes of LA/Ventura
counties, as well as northern San Luis Obispo county.
Our next storm system and associated cold front will bring
steady rain to the Central Coast by Saturday afternoon,
then pushing into LA/Ventura counties Saturday night. The system
will move through the region fairly quickly, with just lingering
snow showers on the north facing mountain slopes by Sunday
morning. This upcoming storm is colder but less moist than
our past storm, with precipitable water values peaking around
0.8 inches. However, this system does have some dynamical
support with a strong 140 knot jet over the region and orographic
support with S-SW winds 25-35 knots in the boundary layer. In
addition, 500 mb temperatures fall to between -25 and -28 degrees
Celsius over San Luis Obispo County by Saturday evening, resulting
in lifted index values between -1 and -3 and CAPE values between
300-400 J/kg. This is enough instability to warrant the addition
of a slight chance of thunderstorms Saturday evening across San
Luis Obispo County.
Rainfall estimates for this next storm (Saturday through Sunday
morning) are expected to range between 0.50 and 1.00 inches
for most areas, with locally up to 1.50 inches in favored
foothill/mountain locations. Peak rainfall rates generally
expected to remain in the 0.25-0.50 inch per hour range, except
locally higher in San Luis Obispo county if thunderstorms develop.
Two factors that could enhance rainfall rates are the very
energetic 140 knot jet and some instability noted along the front,
with CAPE values in the 300-400 J/kg range holding all the way
south into LA county.
In evening update, will also upgrade Winter Storm Watch to Winter
Storm Warning for the local mountains. Snow levels will begin
around 5000 feet, but are expected to drop as low as 3000 to 3500
feet by Sunday morning. Snowfall accumulations of 6 to 12 inches
are expected for elevations above 5000 feet, with minor
accumulation of a couple inches possible at pass level (including
I-5 near Grapevine) by late Saturday evening into Sunday morning.
In addition, there will be southwest winds gusting up to 45 mph
which will likely cause reduced visibilities in blowing snow. As a
result, dangerous winter driving conditions are expected in the
local mountains on this very busy holiday weekend.
*** From previous discussion ***
Sunday will clear fairly quickly later in the morning and afternoon
sunshine looks likely. It will be few degrees cooler with 560 dam
heights overhead and max temps will only reach the lower to mid
50s. Yet another system approaches the area on Sunday night
bringing increasing cloudiness.
Clouds will overspread the entire area Monday and precipitation
will begin in the morning. Early estimates are for one half inch
to an inch of rainfall with the potential for more. Snow levels
drop to around 2500' late Monday night into Tuesday morning and 6
to 12 inches of snowfall is possible. Monday's max temps will
again be confined to the lower to mid 50s for most coast and
valley.
.LONG TERM (TUE-FRI)...24/140 PM.
There is lower confidence in the exact timing of further impulses
Tuesday through Friday as the ensembles have significant spread,
probably due to fast moving upper level flow. What appears to be
the most likely scenario for now would be an upper level 550 dam
closed low dropping down the coast until is just to our west by
Thursday. Uncertainty in the timing and exact placement leave the
extended forecast with a chance of rain every day in most
locations.
There is much higher confidence in the extended temperature
forecast, as max temps will remain 10 to 15 degrees below normal
with the coasts and valleys remaining in the 50s.
&&
.AVIATION...25/0035Z.
At 0020z at KLAX, there was no marine layer or inversion.
Moderate confidence in TAFs. Cigs will likely bounce between VFR-
MVFR for most coast/valley TAF sites through the period. Moist
low level atmosphere will continue to bring 20-30 percent chance
of light showers for most areas on Saturday, with higher
probability of steady rain moving into KPRB and KSBP on Saturday
afternoon, along with a 20 percent chance of cigs lowering to IFR
during that period.
KLAX...Moderate confidence in TAF. MVFR cigs likely to return
tonight and linger through much of the day on Saturday. There
is a 20-30 percent chance of light showers on Saturday.
Good confidence that any easterly wind component late tonight or
early Saturday morning will be below 8 knots.
KBUR...Moderate confidence in TAF. MVFR cigs likely to return
tonight and linger through much of the day on Saturday. There
is a 20-30 percent chance of light showers on Saturday.
&&
.MARINE...24/910 PM.
Across the outer waters, NW winds have dropped below Small Craft
Advisory (SCA) level this evening. Winds will switch to the SW
Sat morning, and by Sat afternoon reach SCA levels. By Sat night,
winds will switch back to W to NW, staying at SCA levels. Sun
morning, winds are likely to fall below SCA levels. South of Santa
Rosa Island, there is a 30% chance that winds will not drop below
SCA levels. By Sun night, there is a 40% chance that W to NW SCA
level winds return and last thru at least Tue morning. Seas will
be close to SCA level through Sun afternoon.
Across the inner waters north of Pt Sal, SCA level SW winds Sat
afternoon/evening are likely, then switch to NW Sat night and drop
below SCA levels Sun morning. There is a 30% chance of SCA level
NW winds Mon morning thru at least Tue morning. Seas will be close
to SCA level through Sunday night at the westernmost portion of
the zone.
Across the SBA Channel, there is a 30-40% chance of SCA level W
winds Sun and again Mon morning thru Tue afternoon. Otherwise,
winds and seas will remain below SCA levels.
Across the inner waters south of Pt Mugu, there is a 30-40%
chance of SCA level NW winds late Sat night thru Sun morning, then
again Mon morning thru Tue afternoon. Otherwise, winds and seas
will remain below SCA levels.
